Description

Dual tone phone dialing business card

The utility model be about a kind of can storing phone number, and the once triggering by dialing button on the business card changes the multidigit telephone number into the dual-tone multifrequency telephone dial tones and sends, thereby finishes the invention to the business card of program-controlled digital telephone switchboard dialing.

The business card of plain paper printing has been brought into play a lot of effects in human communication.But facing to the telephone number of a lot of numeral of printing on the business card, need to use more than ground of telephone keypad to dial, not only dial speed is slow, also might dial a wrong number.The electronic notebook that has has the function of automatic telephone dialing, and this function is to utilize program-controlled digital telephone switchboard can directly receive the characteristics of dual tone phone dialing tone, directly calls by telephone microphone.Though but the electronic notebook storing phone number also can be dialled automatically by the dual tone phone dialing tone that sends, also need a plurality of operating procedures when using, not really easy, and the price height, light and handy unlike business card again, be easy to carry.

Double-tone frequency described in the utility model or title Dual Tone Multifrequency, be meant the signal that the sinusoidal signal by two different frequencies combines, meet dual-tone multifrequency 4 * 4 coded systems or 3 * 4 coded systems of CCITT (CCITT) suggestion.

The purpose of this utility model just provides a kind of like this business card, in the business card of plain paper printing, embed electronic circuit and ultra-thin circuit element, make business card can store a plurality of specific telephone numbers, only need touch dialing button corresponding on the business card during use can change number storing into the dual tone phone dialing tone and send, and finish automatic dialing to program-controlled digital telephone switchboard, dialing procedure need not to operate the electricity machine dialing keyboard of living.But such business card promptly has behind the electronic notebook storing phone number characteristics of dialing automatically, and operation is easier, and cost is low, can do lightly as common business card again, is easy to carry and gives, and dial speed is exceedingly fast, and accomplishes that really zero defect dials.

The profile of dual tone phone dialing business card of the present utility model is similar to common printed business card, laminar business card has printable front and back, just embed in the middle of business card and comprise that substrate, dialing write the element of incoming interface by strong, acoustical generator, battery, electronic circuit, number, described dialing button, acoustical generator, battery, electronic circuit, number are write on the substrate that incoming interface all is installed in insulating material; Described electronic circuit is made of dual toned circuit, the audio amplifier circuit with many sets of numbers memory, and the output of dual toned circuit connects audio amplifier circuit, and audio amplifier circuit output connects acoustical generator, acoustical generator finally just the signal of telecommunication change sound into; Described number is write the number memory that incoming interface is connected to dual toned circuit, is used for write device and writes incoming interface by number and write number to number memory; The input of keyed jointing dual toned circuit is pressed in described dialing, and a plurality of numbers that printed on a plurality of dialing buttons and the business card are corresponding one by one, and the effect of dialing button is by the dialing button once triggered the dial-out of promptly finishing a number; Battery is a power electronics.

Business card is after being completed for printing the back and with the number write device of a special use coding of the telephone number (comprising pager number) that business card printed being write the number memory that incoming interface writes electronic circuit by number, and business card just can normally use.The dialing that clicks corresponding number when calling is by strong, be converted to the sound of dual-tone multifrequency by acoustical generator by the signal of telecommunication of dual toned circuit output, business card is during near the microphone of phone, the dual tone phone dialing tone promptly is sent to program-controlled digital telephone switchboard by telephone line, has finished a dialing.

Based on characteristics of the present utility model, so long as deposit the telephone number of business card in, no matter how long, only need promptly to have finished the process of transmitting of multidigit number by the one-stage dialing button, so it is easy to dial, especially very long telephone number, once dialled continuously fast, can not dial a wrong number.And circuit is simple, and cost is low, to be suitable for widespread usage.

Below with reference to accompanying drawing embodiment of the present utility model is further described.

Accompanying drawing 1 is a dual tone phone dialing name card structure schematic diagram in the utility model.

Accompanying drawing 2 is theory diagrams of electronic circuit in the utility model.
